How to create a form by full declaration?

Question

Django

I'm learning django, going through the creation of forms through the full declaration. Unable to implement. In routes, I can't set 'as.view()' for the BbForm class, I get an attribute error. If I set the path without this, I get the error ''BbForm' object has no attribute 'get'' because it's a class. If in the class I set a function to receive get, it does not work.
I will attach screenshots of urls.py and view.py. In the controller, I added the path to the form template and the form class, but it doesn’t give anything, but as I understand it, this error will happen later when I remove this one.
How to set the route correctly or how to style the class correctly so that this form creation method works?
